General description of drag chain conveyor
Drag Chain conveyors, also called En Masse Conveyors, are suitable for the movement of bulk materials when the product is required to be contained, and have the requirement of no contamination of the environment.
The chain conveyors are manufactured to work horizontally, inclined, or vertically. They fulfill the functions of an elevator in the latter case.
Depending on the capacity and requirements of the en masse conveyor, they can be single-chain strands, double-chain strands, or more-chain strands.
It adopts high-strength materials for the internal lining with steels of the hardness of 400 to 600 Brinell. The drag chain flight is made by the material of UHMW PE. They are in different thicknesses.
Composition of drag chain conveyor
Drive head
The Drive Head is a fundamental part of the chain scraper drag conveyor. It is the sector where the power of the drive unit is transmitted. The sprocket used is commonly made of SAE4140 heat-treated steel or equivalent. It is supported at their ends in boxes.
The sprocket could be a whole unit, and also could be split to facilitate replacement without the need to disassemble the complete axis of the head.
The chain sprockets have an odd number of teeth, to increase their useful life and are subjected to thermal treatments.
In addition, the chain wheel sprocket teeth have a mold. It fulfills the function of unloading the material that may remain between the chain and the top. At the time the flour or adherent materials are transported.
Tensioning head
The manufacture of these components is of the utmost importance. Since it is where the tensioning of the conveyor chain is carried out. They are of strong construction and their main characteristic is the tensioning system by means of a screw sized for each particular case.
Transport channel
It is a very effective system for the construction of transport Channels. It is based on a system of multiple punching dies, allowing a much more efficient production.
The assembly is done by means of mounting devices, which allows ensuring that all the channels are identical to each other and they are interchangeable with each other. They are manufactured by different sheet thicknesses and install the wear bearings with each need.
They have inspection covers with standardized protections.
In the case of a simple transport, can place the return guides of the chains in a “V” shape to ensure even wear on the entire section of the UHMW PE attachment of the chain. They are generally made of steel SAE5260 or SAE9260 and are supported on a standard U profile fixed on the sides.
Special Designs
The chain drag scraper conveyors can be designed for different uses and applications.
They are built in SAE 1010 steel, galvanized sheet, or AISI stainless steel.
They can be straight, inclined, curved type bulk-flow, single or double bottom.
